Alpha-numeric Subject IDs?

[jarvis24]

The help file should read "numeric" not alpha-numeric. Note also that subject IDs are currently limited to a maximum value of 32000. It's a bug that alpha-numeric and IDs greater than 32000 are recorded as 0. This will be fixed in the next version due out this fall. In case it helps for now, there is an option on the tools menu called "Overwrite Warning" that will at least warn you in the case that you are running an identical subject ID (which would occur in these situations as all IDs would be seen by DirectRT as "0").
